Last June, Timo Brinschein bought a Qu4tro electric skateboard with hopes of using it for fun and commuting duties. Unfortunately, while the skateboard itself worked well, the remote had many shortcomings.
Since replacing the skateboard’s controls entirely was out of reach, he instead settled on the “small” job of reverse engineering and swapping out the wireless controller for one of his own designs.
The resulting build uses an Arduino Nano as the brains of the device, along with the well-known nRF24L0+ module for wireless communication. Everything is housed inside a custom 3D-printed enclosure.
